The planet Mercury is grey, similar in colour and general appearance to our moon.
Red Mercury is a chemical made of Iodine and Mercury. It was used as a medicine a long time ago before people realised it was actually poisonous. It is either in the form Mercury(I) iodide or Mercury(II) iodide.

∙ 8y agoMercury red (usually called red mercury) is a hoaxsubstance of uncertain composition purportedly used in the creation of nuclear bombs. It does not exist, so it could not be in thermometers.

Red thermometers are alcohol, with a dye. Invented in the 1600's. They're far less toxic or dangerous than the mercury thermometers (mercury is silver) if broken. However, they are more difficult to make, as they require a thinner capillary tube for the alcohol.
The question implies that a thermometer might be both red, and silver -- this does not seem likely. Perhaps the question needs to be re-asked in a way that is more specific. Just what is red outside, but silver inside? Do you mean that a red thermometer broke and somehow it now looks silver inside (which might happen once the alcohol has evaporated away)? Or do you mean that the writing on the outside of a thermometer is red but there is a column of silver (mercury) inside?

If you are referring to thermometers containing a red liquid, that is alcohol with red dye added, not mercury.

∙ 8y agoNo, mercury is silver. If you have a red liquid in your thermometer, it's alcohol with a dye in it. It's cheaper and safer than mercury, but not useful for high temperatures.
